Adding up a sum of 2 numbers into A Masked Textbox

I am trying to add the sum of two numbers such as 350 + 400 to a Masked Tex开发者_Go百科tbox using a button. I am sorry I am pretty new to C#. Any help is appreciated. Thanks

private void button11_Click(object sender, EventArgs e)
{
   maskedTextBox2.Text.Sum = 350 + 400
}

You just need to set the MaskedTextBox.Text property. Note that the result of 350 + 400 will be of type System.Int32; however, MaskedTextBox.Text is a System.String. C# will not perform the type conversion implicitly (you'll get a compile-time error), so you need to convert the result of this addition to a string. Here's an example:

private void button11_Click(object sender, EventArgs e)
{
    maskedTextBox2.Text = (350 + 400).ToString();
}

For more information on types, see this MSDN page.

private void button11_Click(object sender, EventArgs e)
{
   maskedTextBox2.Text = (350 + 400).ToString();
}

masketTexBox2.Text = (350+400).ToString();

This can help. Appending value to textbox control is done throught .Text property. And at the end, I just converted sum into string

Try this:

private void button11_Click(object sender, EventArgs e)
{
   maskedTextBox2.Text = (350 + 400).ToString();
}

You really just want the sum to show up in the textbox, right? So really, you just need to work with the Text property of the box.

private void button11_Click(object sender, EventArgs e)
{
   maskedTextBox2.Text = 350 + 400
}

If the .Text property of maskedTextBox2 is a string, it will not have a .Sum property.

Try this:

private void button11_Click(object sender, EventArgs e)
{
    maskedTextBox2.Text = (350 + 400).ToString();
}

Like this?

public void button_Click(object sender, EventArgs e)
{
    maskedTextBox2.Text = (350 + 400).ToString();
}

Unless there is some format of the MaskedTextBox that is preventing the assignment, that should be fine.
